Cuphea is a genus of about 260 species of annual and perennial flowering plants native to warm temperate to tropical regions of the Americas. The species range from low-growing herbs to semi-woody shrubs up to 2 m tall.
Some species of Cuphea are used to produce cuphea oil, of interest as sources of medium-chain triglycerides. Early attempts at commercial production have focused on an interspecific hybrid population derived from C. lanceolata and C. viscosissima.
Botanist Shirley A. Graham, currently of the Missouri Botanical Garden, has published widely on the genus. Among Graham's Cuphea contributions are two volumes in the series Systematic Botany Monographs.Selected species
